I think the request should be XML and not 'string' data. This would allow services/clients to use the full set of XML api's to look at requests/responses. (Otherwise, why are we messing with this bloated XML stuff anyway?)

Yes, I agree with you but I don't know how to do it. I can have the Document or the String of the <Request> element but how I integrate it in a nmwg message? I guess I should use the org.ggf.ns.nmwg.base.v2_0.Element class but it wasn't work.

So, any help for adding the <Request> element inside an <aa:subject> element? :-)

To do this you would need to add the necessary objects and handlers to the nmwg object structure.

Or stop using the object marshaling model and just use dom directly or perhaps a push-pull model... Not sure where that is on the Java developers plans, but the marshaling model has obviously shown itself to be a pain in more ways than one and I don't think we should be crafting message formats due to this implementation limitation. (Especially given the fact that the main Java developers have already expressed the wish to remove it.)

I think you can use dom directly when you're generating a nmwg message for sending to a perfSONAR service. But, when a pS service receives it, it will launch an exception because it doesn't know how to model the message with nmwg objects. Please, fix me if I'm wrong...

Probably the short-term solution in the Java implementation is as Jason says: Add the needed objects into the nmwg library.

But, in this case, I prefer to use 'string' data. Why? Because I don't want to model all the XACML objects into the nmwg library. Too many objects!

I agree with you that the request should be XML and not 'string' data, but so far, I don't see the way of doing it.

Regards
